最早发现铅的毒性约是公元前2世纪,人们发现当犬大量吸入铅炉中飞出的铅粉后可造成死亡,此后人们对铅中毒的症状及预防开始有了初步的认识。 进入本世纪20年代,四乙基铅被加入到汽油中用作抗爆剂,导致自然界中铅的大量累积,对人体的危害也日甚一日。因此,在本世纪六、七十年代,国内外学者对铅与人类健康之间的关系从各方面进行了广泛而深入地研究。八、九十年代,随着科学方法和技术手段的提高,对铅的危害有了进一步的认识:目前认为铅的毒性作用主要是脶害
The earliest discovery of the toxicity of lead was about the 2nd century BC. It was found that when a dog inhaled a large amount of lead powder from a lead furnace, it could cause death. Since then, people have begun to have a preliminary understanding of the symptoms and prevention of lead poisoning. In the 1920s, tetraethyl lead was added to petrol as an antiknock agent, which led to the accumulation of a large amount of lead in the natural world. The harm to the human body is also getting worse day by day. Therefore, in the 1960s and 1970s, scholars at home and abroad conducted extensive and in-depth research on the relationship between lead and human health. In the 1980s and 1990s, with the improvement of scientific methods and technical means, there was a further understanding of the hazards of lead: At present, it is considered that the toxic effects of lead are mainly harmful to the environment.
